+krnel Thank you for commenting. I recognize and appreciate what you are saying. I am not disparaging people wanting to expand their skill set and learn new trades. That is admirable. I am merely stating that if we all tried to be completely self sufficient, that would be the antithesis of a thriving market economy. Specialization is entirely necessary and requisite for there to be marked economic growth and development.

I also love that Robert Heinlein quote! Cheers! :-)
